Hematological FISH probes offered
Interphase fluorescence in situ hybridization (IFISH) tests are available that can detect aberrations not apparent by G-banding analysis of chromosomes. Both metaphase and interphase cells can be examined by IFISH. IFISH tests cannot replace G-banded chromosome analysis, which detects abnormalities not targeted by the IFISH probes. Thus, the IFISH tests are best used as a complement to G-banded chromosome analysis and can be done using the same sample you send for karyotyping (1ml heparinized marrow). IFISH request form.
We offer the following probes for FISH testing of Hematologic disorders:

| CLL (or SLL) | del(6q), del(11q), trisomy 12q, del(13q), del(17p) | MYB, ATM, CEP12, D13S319, TP53 |
| MDS (or CMML) | del(5), -7 or del(7), +8, del(20) | EGR1, D7S486/CEP7, CEP8, D20S108 |
